"If any of the three of us lose our home state … I think you have a very, very badly weakened candidacy," Gingrich said on Fox News last month.

"Given the chaos of this race, I don't want to say anything. But I am willing to say I think it is extraordinarily important to win your home state, and it has all sorts of underlying impact if you don't," he added.

Gingrich has campaigned heavily in the state in recent weeks, leaning on former presidential candidate and fellow Georgian Herman Cain at some campaign stops.

"We’re here because we believe Newt Gingrich should be the next president of the United States in America," Cain told a crowd in Cumming, Ga., last week. “And contrary to what the mainstream, lame-stream, lapdog media want you to believe, he can pull it out."

The former House Speaker has been optimistic about his chances in the state, telling a voter last week in suburban Atlanta that he was confident in his political network.

"I would hope to win here and I think, given the years that I spent both helping represent the state in Congress but also helping grow the Republican Party, I think I have some reasonably good likelihood of winning here," said Gingrich.
